So Jipe am I reading this right? Are you suggesting that this kamoya product is "useless" and "outrageously priced," and if so is this based on actual, real life experience with the product, or speculation? I think Kamoya (Kuosac too) often innovate, and their approach is worth some consideration and thought. Kamoya was likely one of the first to come up with a radically different design on Brompton's rear suspension, which was then grossly copied by others. Perhaps having to spend over US$250 on a multiS G5 front suspension would produce more outrage in at least some folks than this $95 one would if it works fine, as ugly and heavy as it may be

To continue a friendly argumentation I found some videos. Note that Kamoya has a "silky" version aimed at absorbing as much chatter as possible, and a stiff "super" version.
